I had a similar procedure but a slightly bigger cyst. If you search the forum you'll find a couple posts about it.

It was in my pre-cycling years though.

I suggest that you take it a little easier than you'd like after the operation, as the side effects can be sneaky. I was operated on a Monday and had a doctor's order to stay home for ten days. On the Thursday, I went teaching, which was fine, but I decided to talk home - an energetic 20-minute walk with a few kilograms of groceries in my hands and a laptop computer on my back - and I was back in the hospital on the weekend with a fever, all-over muscle soreness, and fear of an infection. It turned out that I was okay, but it could have been worse. I could have been just a bit more careful...

Good luck! You'll feel much better after the operation!!!
